Vintage HH Scott LK-72 Stereo Laboratory Tube Amplifier – Totally Redone. UPDATE – Almost forgot, comes with an original manual/schematics for this unit. This was my every day amp for…. It was in my office for another 1. I have had 3 other lk-72′s but I always kept this one. It just sounded perfect to me. The LK-72 is one of my 2 favorite vintage tube amps, along with the Sherwood S5000 series. Just has a great sound, layout and set of functions. Not that hard to work on either. This was the first amp my current tech worked on for me, YEARS ago. Because of this I no longer have all of the paperwork. However, you can see all of the work he has done and I will detail it as much as possible. I have a very detailed tech who doesn’t like to do things 1/2 way. He also refuses to use parts he does not like/he is not familiar with. The value of having a competent tech should not be underestimated. He is the 4th one I have used and by far the best. Take a look at the bottom of the unit POST updating. That is some neat work. NOTE ON COSMETICS – The front panel is Very Good. The paint used on these is REALLY delicate so clean it gently! Or not at all! The front panels on these are often pretty beat, not this one. The only real wear is around the Volume Knob, which is ALWAYS the case. This unit has the PULL on/off switch which I personally love. The 12AX7′s are vintage Mullards made in England. The 7591′s are Tung Sol (Russia). 6GH8′s are vintage Amperex (France). 3X CE CAN Replacement CAP’s (see pics). SEE PHOTOS of Bottom for other replaced bits (pretty extensive). I tried other 7591′s but for this amp I thought the Tung Sol’s were the best. This has been in my rotation for a good 2 or 3 years without issue. This is a great vintage tube amp in every regard. Alot of work went into making it such. Some day something on this will not work right but that is true of every piece of vintage audio equipment. The advantage with this unit is 1 all the stupid stuff has already been taken care of and 2 as it is a tube amp it is FAR easier to work on and tubes themselves are pretty simple to replace. If you have any questions ask them beforehand. I’ll be glad to answer them promptly.
